vEMan - [v]Mware [E]SX [Man]ager provides a GUI for managing ESX servers natively from within your Linux desktop without the need to use Windows vSphere® anymore!
Support vEMan development for v2.0 by gofundme!

Why I started vEMan? Because I hate it to start my Windows VM to manage ESX(i) servers ;o)
vEMan is (maybe) not needed if you use vCenter 5.x: http://kb.vmware.com/kb/2005377
--> vSphere >= v5 has a "web client"
BUT keep in mind that there are caveats...
